The first issue of Ace Comics was published in April 1937, and included the adventures of hunter Jungle Jim written by Flash Gordon writer Alex Raymond, Chic Young's Blondie, and George Herriman's surreal Krazy Kat strip, all three characters going on to appear in every issue of Ace Comics.
The Phantom daily strip, written by Lee Falk and drawn by Ray Moore, then featured in Ace Comics for a 140-issue run, appearing in every issue until the title was cancelled.
As well as Jungle Jim and The Phantom, which ran throughout the series, Hal Foster's knight's tale of Prince Valiant was also a long-running adventure feature, published in issues 26-134.
Other adventure strips that appeared included Zane Grey's Western character Tex Thorne in early issues, the adventures of orphan Tim Tyler in Tim Tyler's Luck and Curley Harper at Lakespur [fr] both by Blondie writer/artist Chic Young's brother Lyman Young.
Later issues reprinted the Flash Gordon-like space adventures of Brick Bradford and The Lone Ranger strip, both transferred from the King Comics title.
Other humor strips included Pete the Tramp by Clarence D. Russell, Tillie the Toiler by Russ Westover, Billy DeBeck's Barney Google, Jimmy Hatlo's They'll Do It Every Time and Paul Robinson's Etta Kett were presented throughout the run, although all of these titles missed the odd issue.
Another classic Golden Age artist whose work appeared in a number of issues was C.C.Beck (creator of Fawcett's Captain Marvel).
